Implemented using libopus for the Opus codec, same as is used in Discord.
This adds the following cvars:
- `voice_chat` On/Off, triggers self-deafen state on server via weaponprefs
- `voice_mode` Activity/PTT
- `voice_selfmute` On/Off, triggers self-mute state on server via weaponprefs
- `voice_inputamp` -30 to 30, scales input by value in decibels
- `voice_activationthreshold` -30 to 0, if any peak in a frame is higher, activates voice
- `voice_loopback` On/Off, plays back local transcoded voice
- `voice_proximity` On/Off, enables proximity effects for server
- `voice_distanceattenuation_distance` distance in fracunits to scale voice volume over
- `voice_distanceattenuation_factor` distance in logarithmic factor to scale voice volume by distance to. e.g. 0.5 for "half as loud" at or above max distance
- `voice_stereopanning_factor` at 1.0, player voices are panned to left or right speaker, scaling to no effect at 0.0
- `voice_concurrentattenuation_factor` the logarithmic factor to attenuate player voices with concurrent speakers
- `voice_concurrentattenuation_min` the minimum concurrent speakers before global concurrent speaker attenuation
- `voice_concurrentattenuation_max` the maximum concurrent speakers for full global concurrent speaker attenuation
- `voice_servermute` whether voice chat is enabled on this server. visible from MS via bitflag
- `voicevolume` local volume of all voice playback
A Voice Options menu is added with a subset of these options, and Server Options has server mute.
The hypothesis for this patch is that the operating system has not actually
finished writing the file to disk when moving the tmp file into place. The
move operation is atomic, but the write is not, even when flushed or using
unbuffered IO. So we reorder these operations, make the old save .bak
atomically and write the new save in place.
I doubt saving this backup will actually be useful given the frequency of
saves in the game, but at the very least it leaves _some_ backup in place in
the event of failure.
